Preheat oven to 325 degrees.
- In a medium sized bowl, cream butter and sugars together. Add eggs and peanut butter, then mix well until the mixture is fluffy and well incorporated. Add baking soda and rolled oats and mix to combine, then fold in the m&ms and chocolate chunks.
- Drop the cookie dough by tablespoonfuls onto a greased cookie sheet (I prefer to grease my pans with a bit of butter but you can also use cooking spray), then shape the cookie dough into balls with your fingers. These cookies tend to spread out a good bit in the oven so be sure to keep them several inches apart.
- Bake the cookies in the preheated oven for 12-15 minutes until the bottoms and edges are starting to brown. Allow the cookies to rest for 5-10 minutes, then remove them from the baking sheets and enjoy!

This Recipe is another treasure I found in grandma’s recipe box. Perhaps I should call them treasure chest cookies?!
